SLElGH-KNEE.

SPECIFICATION forming part of Letters Patent No. 439,370, dated October 28, 1890. Application filed October 22, 1888. Serial No. 288,780. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH APPLEBAKER, of Marshtield, in the county of Wood, and in the State of Wisconsin, have invented certain new and useful Improvements in Sleigh- Knees; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relatesv to sleigh-knees, and will be fully described hereinafter.

In the drawings, Figure 1 is a side elevation ofasleigh-bob embodyingrnyinvention. Fig. 2 is a plan view, and Fig. 8 a vertical section on line 3 3, Fig. 2

A 'are the runners, and B are the knees. These knees are preferably of cast metal, each having a central pillow that is braced front and rear by struts a a, which are cast with it. The base I) of the knee is formed with depending-lugs c,that straddle the runner and receive bolts d, that secure the knee to the runners. Horizontal ears e project from the front and rear of the base, and each is formed with an opening to fit overadowel-pin e, that projects up from the runner. These pins not only serve to fix the knee in position to bring the bolt-holes in the ears d flush with the proper holes in the runner, but also serve to resist strain on the struts a.

The upper end of the central pillow of each knee is bifurcated to form standards f f, each pair of standards receiving between them an end of the bolster O. The inner face of each standard is formed with a rib g, and the bolster is correspondingly grooved, and by the runner of a sleigh having dowel-pins project ing from its upper side, of a knee having horizontal extensions or ears to receive said dowelpins, vertically-pendent lugs for straddling the runner, vertical standards ribbed on their inner sides, oblique struts extending from the .upper ends of the standards and downward to the upper side of the knee, and a strap attached at its ends to the oblique braces and overlaying the bolster so as to confine the end of the bolster between the standards, substantially as described. 7 g

In testimony that I claim the foregoing I have hereunto set my hand, at Marshfield, in the county of Wood and State of Wisconsin, in the presence of two witnesses.

JOSEPH APPLEBAKER.
